I am thinking about putting Airflow Performance fuel injection on my already flying O-320 RV6A. I have talked to Don at Airflow. My question is for you guy's that have put the fuel injection on by yourself. Is it very hard to do? Can a simple man put it all on or should you have someone do it for you? For the guy's already flying with Airflows fuel injection how do you like it and have you had any trouble?
